Abstract
Description
Technical Field
[0001] This utility model belongs to the field of footwear, and more specifically, it relates to a novel removable diabetic foot care insole. Background Technology
[0002] Insoles are padding layers placed inside shoes, often made of materials such as cloth, linen, leather, and silicone, and have functions such as sweat-proofing, cold-proofing, and height enhancement. Currently available insoles are mostly general-purpose and cannot meet the needs of some users with special requirements. For example, diabetic foot patients often experience lesions (ulcerative wounds, etc.) on the forefoot or foretoes. When walking with regular insoles, the injured area is easily squeezed and rubbed against the insole, exacerbating the lesions. Utility Model Content
[0003] In view of the problems in the related technologies, this utility model proposes a novel randomly detachable diabetic foot care insole to overcome the above-mentioned technical problems existing in the existing related technologies.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a novel, randomly detachable diabetic foot care insole, comprising a skin-friendly and breathable layer, an elastic layer, and an adjustable support pad layer that are sequentially bonded together. The adjustable support pad layer is provided with a through groove, and a modular support module is fitted into the through groove. The modular support module can be assembled into the through groove according to the location of the foot injury to avoid the location of the foot injury.
[0006] Furthermore, the skin-friendly and breathable layer is made of natural plant fiber textiles.
[0007] Furthermore, the elastic layer is made of elastic memory foam.
[0008] Furthermore, the inner ring of the elastic layer is provided with a through groove, and a filled breathable layer is installed in the through groove.
[0009] Furthermore, the filled breathable layer is made of loofah sponge or palm fiber material, and the elastic layer is covered with a mesh.
[0010] Furthermore, the modular support module includes multiple support columns, and adjacent support columns can be interlocked and positioned with each other.
[0011] Furthermore, the support column is a hexagonal prism structure.
[0012] Furthermore, the adjustable support pad has an elastic pressure chamber inside the heel position, a flow channel communicating with the elastic pressure chamber inside the forefoot position, and multiple ventilation holes communicating with the flow channel on the top surface of the adjustable support pad.
[0013] Furthermore, the top surface of the adjustable support pad is provided with a groove located above the guide channel, and the top surface of the vent hole is located inside the groove.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, a modular support module is installed in the support pad layer of the insole through a through groove. The modular support module can be assembled in the through groove according to the location of the foot injury to avoid the foot injury location. This prevents the insole from squeezing and rubbing the foot injury location when in use, and can prevent the injury location from aggravating the condition.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0025] Please see Figures 1-4 As shown, this utility model is a novel diabetic foot care insole that can be randomly disassembled, including a skin-friendly and breathable layer 1, an elastic layer 2, and an adjustable support pad layer 3 that are sequentially attached and connected. The adjustable support pad layer 3 is provided with a through groove, and a modular support module is installed in the through groove. The modular support module can be assembled in the through groove according to the location of the foot injury to avoid the foot injury location.
[0026] When in use, the insole can be assembled and adjusted according to the location of the foot injury in diabetic patients (i.e., the assembly and adjustment of the support module is not installed at the injury site), thereby avoiding the injury site. This prevents the insole from squeezing and rubbing the injured area, thus preventing the condition from worsening. The skin-friendly and breathable layer 1 and the elastic layer 2 are flexible structures that do not provide sufficient hard contact and pressure, thus preventing the injury from worsening.
[0027] Specifically, the skin-friendly and breathable layer 1 is made of natural plant fiber textiles. This natural plant fiber is extracted from pineapple leaves. After processing, this fiber is white, soft, smooth, and has a feel similar to silk. It also has the ability to absorb and evaporate moisture more quickly than hemp, making it a superior natural and health-promoting new type of textile material. Many diabetic foot patients suffer from excessive sweating, foot odor, athlete's foot, and other foot problems in their daily lives, often experiencing numbness, pain, and odor in their feet. Pineapple leaf fiber can alleviate bacteria, and various antibacterial agents are combined with the textile material through chemical and physical methods, achieving antibacterial and deodorizing effects.
[0028] Specifically, the elastic layer 2 is made of elastic memory foam, which not only has high elasticity, making the patient's feet softer and more comfortable when in contact with the insole; another aspect is to record the patient's foot shape so that the insole is more soothing and comfortable to use.
[0029] Specifically, the inner ring of the elastic layer 2 is provided with a through groove, and a filled breathable layer 21 is installed in the through groove, so that the elastic layer 2 has breathable properties, thereby improving the overall breathability of the insole.
[0030] Specifically, the filled breathable layer 21 is made of loofah sponge or palm fiber material, and the elastic layer 2 is covered with a mesh. Both loofah sponge and palm fiber materials have good breathability, and the mesh covering can improve the stability of the filled breathable layer 21 installed in the elastic layer 2.
[0031] Specifically, the modular support module includes multiple support columns 31, and adjacent support columns 31 can be interlocked and positioned with each other. The support columns 31 are hexagonal prisms. By setting the support columns 31 to hexagonal prisms, the interlocking of adjacent support columns 31 can be made more stable, thereby improving the stability of the modular support module in the adjustable support pad 3.
[0032] Specifically, the adjustable support pad 3 has an elastic pressure chamber 34 inside the heel position and a guide channel 35 inside the forefoot position that communicates with the elastic pressure chamber 34. The top surface of the adjustable support pad 3 has multiple ventilation holes 32 that communicate with the guide channel 35. When the insole is in use, the elastic pressure chamber 34 can repeatedly contract and elastically expand under the reciprocating pressure of the heel. When the elastic pressure chamber 34 contracts, the gas inside is blown upward through the guide channel 35 and multiple ventilation holes 32. Correspondingly, when the elastic pressure chamber 34 elastically expands, it draws air inward through the ventilation holes 32 and the guide channel 35, thereby generating airflow in the shoe cavity when walking. When the airflow blows across the sole of the foot, it can also circulate air and keep the feet drier.
[0033] Specifically, the top surface of the adjustable support pad 3 is provided with a groove 33 located above the guide groove 35, and the top surface of the vent hole 32 is located inside the groove 33. By setting the groove 33, the top opening of the vent hole 32 is slightly lower than the top surface of the adjustable support pad 3, preventing the top opening of the vent hole 32 from being blocked and sealed by the filled breathable layer 21, which is beneficial to improving the breathability of the vent hole 32.
